Which output does the unique tool provide when duplicate values are present?

The unique tool in Alteryx is specifically designed to identify and retain only the distinct values from a dataset, effectively removing any duplicate entries. When it is applied to a dataset that contains repeated values, the tool processes the data and outputs only the unique values, disregarding all duplicates. This functionality is valuable in data analysis when the focus is on distinct items, making it easier to summarize and understand the dataset without redundancy.

In contrast, the other choices do not accurately represent what the unique tool does. While it may seem intuitive to consider output options like all values including duplicates, or filtered values, those functionalities are not the primary purpose of the unique tool. The key takeaway here is that the unique tool streamlines data analysis by presenting just the unique elements, ensuring clarity and conciseness in reporting.
